I use my power brush all the time to clean rust off steel, clean bolt threads and whatever needs cleaning. This power brush is a upgrade to a 1/2 HP motor which I bought many years ago new but never used. It replaces the 1/4 HP motor my neighbor gave me which I used for many years. I kept the base and square tube riser from the old power brush, then made two cuts in the riser for the 3" angle iron which the new motor sits on, then added straps to hold it down. I works very well.
Warning, use a face shield and wear safety glasses when using any wire wheel brush. I once had a wire somehow get under my face shield and stick in my face right under my safety glasses frame.
